SPECIFICATION forming part of Letters Patent No. 231,078, @lated August 10, 1880.

Application filed April 9, 1880. (Model.)

To all whom @t may concern:

Be it known that I, CHARLES METZLR., residing at New York, county and State of New York, have invented certain new and useful Improvements in Machines for Sizing Muslin, of which the following is a specification.

This invention has forits object to apply glue size to musliu in rolls, so as to prepare it to receive oil-paints, for the purpose of making opaque window-curtains aud other purposes; and it consists of a series of tension and guide rollers, adjustable pressure-roller, adjustable size-applying roller, and a series of dryingdrums, so constructed and arranged that as the muslin is drawn from the roll over the various devices it is properly stretched so as to remove therefrom all creases. The size is applied to one of its sidesin the required quantity, and it is held in a straight and even condition as it passes over the drying-drums until it is sufficiently dry to be wound onto aroll by the winding device, all of which will be fully hereina-fter described by reference had to the accompanying drawings, forming part of this specification, in which- Figure l is a longitudinal sectional elevation of my improved machine for sizing muslin, and Fig. 2 is a transverse section through the line a' ay, Fig. 1, showing the pressure and size-applyin g rollers.

The muslin from the roll a passes rst between the series of tension bars or rollers b b, the upper one, c, of which is provided with oblique grooves or a right and left handed screwthread, starting from its center to the two ends. Said grooves or screw-thread act ou the muslin to stretch it laterally and so remove any creases, allowing it to pass over the guideroller d in a perfectly smooth condition, in which condition it passes over the sizing-roller e. This roller is arranged to revolve in the trough e', in which the glue size is placed, and it has a pulley, c2, on the end of its shaft, projectin gbeyond the sideframe,j', of the machine. This pulley is connected to a pulley, d', secured to the projecting shaft of the guide-roller d, by means of the belt g, the two pulleys d', and c2 being so proportioned in size that the sizing-roller c is caused to revolve at the same speed or a little faster than the speed at which the muslin passes through the machine, the

upper surface of the roller moving in the same direction as the musliu, so that it properly applies the size to the under side thereof, as the lower part of the roller revolves in the glue size placed in the trough c all the time.

The muslin in this condition-that is, with the wet size on it--would, if left to itself, get out of shape; but it is kept under tension until dry by being drawn from the sizing-roller c over the roller h and around the drum i, the large smooth surface of which prevents the muslin creasing or getting out of shape. From the drum it passes over the rollers h h2, under the second drying-drum, t', over the roller h3, and from it to the winding-up device. These drying-drulns fi i are supplied with steam for drying the size which is on the outside surface of the muslin, and the rollers h h l1,2 are made hollow, and they have a stream of cold water flowing through them, as shown at h and h', or have cold water applied to their surfaces, as shown at h2, to prevent the size adhering to their surfaces. The water in the size, by the action of the heated steam-drums i 'i' in drying the sized musliu, is evaporated and condenses on the surfaces of the rollers ZL h', which remain cold by the cold water flowing through them, thereby keeping them moist and preventing the size adhering` to their surfaces 5 and it is also found, in practice, that the mere fact of keeping the metallic surfaces of rollers cold will prevent the size adhering to them, which may be done by means of cold water or cold air being caused to ilow through them. All of these drying-drums and the water-rollers are fitted with journals to revolve in bearings provided therefor in the side framesfj', and there should be a sufficient number of the drying-drums to thoroughly dry the muslin before it leaves the machine,the number depending on their size and amount of surface to which the muslin is exposed. Only two are shown in the drawings, the others being of the saine construction as those shown, and each one having two guide water-rollers.

The method I employ to apply the requisite quantity of glue size to the muslin, and which is one of the principal features of this invention, is by making the size-roller c and trough e' vertically adjustable, or the roller only, by means of the set-screws ofs e3 passing through IOC) projections on the side frames and bearing against the under side ofthe ends ofthe trough e', or the roller-bearin gs, whereby the roller e is caused to press with more orless force against the under side ot' the muslin. The muslin is further controlled by the adjustable pressureroller 7c, which rotates in sliding boxes in the side frames, ff, between the guide-roller d and the sizing-roller c, said sliding boxes being vertically adjusted by means of the set-`sorews 7c 7c', so the roller 7c presses the muslin more or less downward between the roller d and sizingroller e or the roller k may press on the muslin by its weight only, thus assisting to cause the muslin to maintain its straight and smooth condition, and at the same time making' it bear with a uniform pressure on the sizing-roller e, so that after the machine is properly adj usted a smooth uniform coating of glue sizing is applied to the mnslin by the sizing-roller c.

Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. In a machine for sizing 1n uslin in rolls, the

adjustable sizing-roller e, in combination with the guide-roller d and drying drum or drums t', and water-rollers, constructed and operating substantially in the manner hereinbefore set forth.

2. In combination, the guide-roller d, the size-roller c, rotating` in the trough ef, and the adjustable pressureroller 7c, located between the guide-rollerd and sizeroller e, so as to press the muslin more or less downward between them, substantially as and for the purpose set forth.

3. In a machine for sizing muslin in rolls, in combination, the guide roller d, adjustable pressure roller 7o, adjustable sizing roller e, and drying drum or drums t', and water-rollers, constructed and operating substantially in the manner hereinbefore set forth.

In testimony whereof' I have hereunto set my hand this 5th day of April, 1879.

CHARLES METZLER.
